AApplication filed December. 11, 1911.y Serial No., 665,020.

ToiaZZ whom t may concern.'

Be it known that I, HARRY E. LrvrNesToN, a' citizen of the UnitedStates, residing at Smithville, in the county of Lee, State ofAimprovements in doubletrees and the object of my invention is toimprove the constructionA and increase .the etiiciency of the same.

A further object of my invention is to 4provide a novelform of clip bymeans of 1 vwhich the doubletree may be secured to the vehicle. 4

With these and other objects 1n view my invention will be more fullydescribed, illusof this application.

-proved v doubletree `which trated in the accompanying drawings whichshow a. preferred embodiment of my device and then specifically pointedout' in the claim which is attached to and forms a part In the drawings,Figure 1 is a top plan view of the doubletree.' 2 is arear elevat-ionthereof. Fig. 3` is a detailed perspt tive of the clip. Figi t isadetail perspective Voit-a partially finished clip.

Referring more specifically to the drawings, in .which similar referencelnumerals designate corresponding parts throughout, 10 designates ingeneral the body of my imis preferably formed of wood and the rear faceof which ,is straightI as shown, while the forward face tapers from thecenter toward the ends whereby the central portion of the lbody memberis thicker' than thel ends. By this means the body member isconsiderably lightened while at the same time it is in no way weakened.Extending along the entire length of the rear face of the body member isa strip of 'metal 11- the ends of which are bent about the ends of thebody. member and extended forwardly beyond the same andthen'bentinwardly and rearwardly to form loops`12, the terminals of saidloops being extended along. the forwardinelined faces of the bodymember.v This strip Ais secured in place by means of bolts or rivets 13which are passedthrough the-body' of the strip,

through the body member 10 of the doubletree and also'through theterminals of the strip 11, the same bolts thereby serving both to securethe stripto the back of the doubletree and also to secure the loops inplace.

This metallic strip. is preferably rectangularl in section throughoutits leiigth with the eX- ception of the intermediate loop formingsections which as shown, are circular in section. Flach of the loops isprovided with a. hook 14 by means ofwhich swingletrees may be attached.y

Asa means for attaching the doubletree to a vehicle I have provided animproved clip 15 formed from a single rod of metal bent intermediate itslength as at 16 and having its sides extended in spaced parallelrelation, said side portions being then bent inwardly to cross'eaehother and then rearwardly, thcterminal of one side member eX- tending inparallel spaced 'relation to the 'main portion of the other side memberand in spaced relation therefrom 'in lsuch a mann'er that the free endsof t-he rods are positioned one upon either side of the bight portion 16to which, they are then secured by welding. By this means a clip isformed.

consisting of a. pair of diverging rings connected to each otherthroughout a port-ion of their circumference. This clip is positionedupon the doubletree as best shown in Figs. 1 and 2, in such a-mannerthat the bight por# tions 1S engage one upon either side of the centerof the doubletree and against the inclined faces thereof, while thewelded portion of the clip extends rearwardly beyond the doubletree andis provided with a ring 19 for attachment to the vehicle.

As will be readily seen strain appli'ed-'to the hooks 14 will tend tocause the bight portions 1S of the clip to be drawn together, whichtendency is overcome due to the fact that the 'inclined faces of thedoubletree act to hold the said portions apart. The strain thereforemerely acts to Hatten the rings or loops and thus cause them to bindmore tightly about the doubletree. The metallic strip 11 not only servesto. reinforce the dou'- bl etree and to form loops for the attachmentVof the swingle-tree but also acts as a wear plate to prevent injury tothe doubletree which might otherwise be caused by. the

ring 19.A l

It will therefore be seen that I have provvided an extremely simple andeffective forni of doubletree and one which maybeA inexpensivelymanufactured.v

What I claim is vThe combination wit-h a doubletree having rearwardlyinclined 'forward faces, of a clip for' said doubletree comprising ametalliclportion of one 1s positioned in parallel -spaeed relation tothe side portion of the other, said end portions terminating one uponeither side of the intermediate` bent ortions and being secured theretoby weld- 1ng,said clip being positioned upon the doubiet-ree with theresultant spaced loops thus;

formed bearing,- against the inclined faces yof the doubletree one uponeither side of the `center thereof and'with its welded ortionl extendingrearwardly beyond the` oubletree.

In testimony whereof, I affix my signature, in presence of twowitnesses.
